Triple Stacked Sun - 16th January

I tried another configuration with the Lunt 50 etalon I recently bought, and that is triple stacking it with my existing double stacked SM40 etalons.  The weather was supposed to be good on saturday, but rapidly thickening cloud meant I had very little time for observing and imaging.  I tentatively looked through the eyepiece visually to see whether it would work, tuning the etalons the view was immediately apparent that there was a lot of detail and contrast.  I just about managed to get the image above running on maximum exposure and very high gain before the cloud was too thick.  I really excited to see how this setup performs in good sky conditions...
